Facilitating mobile device payments using product code scanning

ABSTRACT

Provided are computer implemented methods and systems for facilitating mobile device payments using barcodes displayed on mobile devices and scanned by merchants at checkout counters. When a customer is ready to tender a payment to a merchant, instead of using a credit card, cash, or check, the customer activates an application on his mobile device. The mobile device includes or obtains information about the payment system of this merchant. Furthermore, the mobile device includes or obtains information about the customer/mobile device user and then uses these two pieces of information to generate and display a barcode that encodes customer payment information specific to this merchant. The barcode is scanned at the checkout counter and processed to retrieve customer records from a database of the payment processing system. These records are then used to transfer funds between the merchant and customer, obtain discounts, and/or perform other retail transactions.

FIELD

This application relates generally to payment methods using mobile devices in various retail environments and, more specifically, to computer implemented methods and systems facilitating mobile device payments using barcodes.

BACKGROUND

When customers buy product items from various merchants in these merchants' retails environments, such as retail outlets, shopping centers, stores, etc., only a handful of payment methods is available to the customers. Typical examples include credit cards, debit cards, gift cards, checks, and cash. Each one of these payment methods has some drawbacks from cost and/or convenience perspectives. For example, credit cards bear substantial processing fees, while debit cards require availability of funds and sometimes involve surcharges as well. Checks and cash transactions are slow and require additional processing and/or handling. All these drawbacks interfere with retail transactions and add some level of dissatisfaction.

At the same time, a customer typically visits the same group of stores repeatedly, and these payment transaction fees tend to accumulate. While some stores try to issue their own credit-like account systems and employ banks to help them in this endeavor (e.g., Sears—Chase VISA), many stores are simply too small to build and operate systems similar to the ones provide by the major credit card companies and/or banks. Furthermore, a typical customer repeatedly visits multiple retail outlets. Requiring the customer to continuously carry multiple retail cards (or other security/transactional devices) each one being specific to only one of these outlets may be difficult, if not unreasonable. For example, a typical customer may use a few gas stations (e.g., depending on his location), a few grocery stores (e.g., depending on preferences), a few electronic stores (e.g., depending on current sales and promotions). Complexities introduced by store specific account systems may quickly offset any costs savings or inconvenience associated with traditional methods of payments and may make the overall experience even worse.

DETAILED DESCRIPTION

Various computer implemented methods and systems for facilitating mobile device payments using barcodes are described herein. Recent proliferation of mobile devices (e.g., cell phones/smart phones and other similar devices) that are capable of generated and displaying various optical codes (e.g., barcodes) allows implementing these novel methods and systems. Most customers shopping in today's retail environments carry such mobiles devices.

Product codes are typically provided as barcodes, such as linear barcodes and two dimensional barcodes, as well as human readable alphanumeric code. Displaying a barcode may involve processing information to encode into a barcode image. The local processing may be performed using various software applications installed on the mobile device. For example, the Universal Product Code (UPC) or European Article Number (EAN) may be used. UPC is a barcode symbology widely used in North America and other countries for tracking trade items in stores. Its most common form, the UPC-A, consists of 12 numerical digits, which are uniquely assigned to each individual trade/product item. Each UPC-A barcode consists of a scannable strip of black bars and white spaces, above a sequence of 12 numerical digits. No letters, characters, or other content of any kind may appear on a standard UPC-A barcode. The digits and bars maintain a one-to-one correspondence. In other words, there is only one way to represent each 12-digit number visually, and there is only one way to represent each visual barcode numerically. EAN is another example developed as a superset of UPC and adding an extra digit to the beginning of every UPC number. EAN-13 barcodes also indicate the country in which the company that sells the product is based using leading digits. EAN and UPC barcodes are currently the only barcodes allowed for scanning trade/product items at the point of sale. However, other codes may be available in the future and within the scope of this document.

One having ordinary skills in the art would understand that the term “scanning” is not limited to printed codes having particular formats but can be used for codes encoded electronically and using various other means. For example, product codes may be in the form of the recently developed Electronic Product Code (EPC) designed as a universal identifier that provides a unique identity for every physical object (not just a trade item category) anywhere in the world. It should be noted that EPCs are not exclusively used with RFID data carriers. They can be constructed based on reading of optical data carriers, such as linear bar codes and two-dimensional bar codes, such as Data Matrix symbols. For purposes of this document, all optical data carriers are referred herein as “barcodes.”

Scanning a barcode may involve capturing an image of the barcode using a simple imaging device installed on a mobile device, such as a digital camera. The image may be then processed on the mobile device to retrieve corresponding product information or sent to the server for further processing. The local processing may be performed using various software installed on the mobile device. In certain embodiments, a mobile device may contain a local database to match the retrieved product information with additional information about this product. However, because of variable nature of this additional information (e.g., pricing, product description), a mobile device then typically transmits the retrieved product information to the server and then receives some additional information from the server.

As stated, many mobile devices have wireless communication capabilities. In addition to being capable of transmitting voice-based signals, many modern cell phones have internet connectivity using cellular networks (e.g., 3G, 4G) as well as Wi-Fi and other types of networks. Some additional examples of such networks are described below with reference to FIG. 1. Wireless communication may be used to transmit retrieved product information to a payment server, receive replies, and transmit authorizations. Overall, various data may be exchanged between the mobile and payment server as well as other servers during operations of the method.

Before describing various methods and associated operations, a brief description of a computer network. Specifically, FIG. 1 illustrates an example network segment for implementing various aspects of methods and operations for facilitating mobile device payments in a retail environment using a mobile device. As shown, multiple mobile devices 102 a, 102 b, 102 c may be configured to display barcodes 114 a, 114 b, 114 c. Various examples of barcodes are described above. Mobile devices 102 a, 102 b, 102 c communicate with payment server 106 via network 104. Payment processing server 106 is a part of the payment processing system, which may include payment account database 108 and one or more checkout counters 112. Network 104 may be also used for communication among various components of the payment processing system. Network 104 may take any suitable form, such as a wide area network or Internet and/or one or more local area networks (LAN's). The network 104 may include any suitable number and type of devices, e.g., routers and switches, for forwarding commands, content, and/or web object requests from each client to the online community application and responses back to the clients.

The methods describe herein may also be practiced in a wide variety of network environments (represented by network 104) including, for example, TCP/IP-based networks, telecommunications networks, wireless networks, etc. In addition, the computer program instructions may be stored in any type of computer-readable media. The program may be executed according to a variety of computing models including a client/server model, a peer-to-peer model, on a stand-alone computing device, or according to a distributed computing model in which various functionalities described herein may be effected or employed at different locations.
